The calculation of diluted earnings per share for the years ended December 31, 2025, 2024 and 2023, excludes the incremental effect related to certain outstanding stock-based compensation grants due to their anti-dilutive effect. When a net loss is reported, our basic weighted-average shares are used to calculate diluted earnings per share, as dilutive shares would have an antidilutive effect and result in a lower loss per share.

About Earnings Per Share Disclosures

The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.

Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
